In the exhibit "1991... (Memorial Promenade)" Galerie Thomas Schulte, on the occasion of its 20th anniversary, once again assembles some of the most important protagonists of its programme from the first seminal years. Rebecca Horn, Richard Artschwager, Sol Lewitt, Robert Smithson, Allan McCollum or Gordon Matta-Clark have not only staged some of the most outstanding exhibitions of the gallery, but over the years have constituted the fundament of its programmatic and artistic concept, from which new positions have been emerging since.
